What is the primary function of bronchodilators?

To increase blood pressure
To relax bronchial smooth muscle
To stimulate the immune system
To decrease heart rate

The correct answer is: To relax bronchial smooth muscle

Bronchodilators are medications specifically designed to relax the smooth muscles in the bronchioles, which are the small air passages in the lungs. This allows for increased airflow and easier breathing. Therefore, options A, C, and D are incorrect as they have no effect on the bronchial smooth muscle and may even have the opposite effect. Bronchodilators are not meant to increase blood pressure, stimulate the immune system, or decrease heart rate. They are solely used to treat respiratory conditions that involve constricted airways.
